I have been focusing a lot on security and privacy issues in this year's columns so far, but I realize some of you may expect a different kind of topic from me (or maybe are just tired of all this security talk). Well, you are in luck. more>>

Please send information about releases of Linux-related products to [email protected] or New Products c/o Linux Journal, PO Box 980985, Houston, TX 77098. Submissions are edited for length and content.

We have a free eBook available for you to download today: DevOps for Dummies. more>>

I'm sure many of you have at least heard of Tiny Core Linux—legends of how small it is, how little it takes it to run a system with it and even now how it's been ported to run on Raspberry Pi. It's an esoteric minimalist distribution. more>>

Several computer algebra systems are available to Linux users. I even have looked at a few of them in this column, but for this issue, I discuss OpenAxiom. OpenAxiom actually is a fork of Axiom. Axiom originally was developed at IBM under the name ScratchPad. Development started in 1971, so Axiom is as old as I am, and almost as smart. more>>

Consider this traditional scenario: in today's competitive world, dynamic business requirements need flexible and rapid provisioning of IT resources. Along with flexibility, traditional IT environments need new resources to support the dynamic workloads of applications. more>>

Please take a few moments to cast your votes in this year's Readers' Choice Awards. more>>

There's an old saying in the real-estate business that the three most important things in a property are location, location and location. We can assume this is still true when it comes to real estate, but it also is increasingly true when it comes to Web applications. more>>

If you're like me (and you're a Linux Journal reader, so you may actually be like me), you probably rotate through your cell phones and/or tablets every couple years. These little devices are so convenient and have been consistently dropping in price, while their power continues to go up, so you may have a few older devices sitting in a drawer. more>>

I am a visual learner. When I try to teach something, I naturally like to use visual examples. That usually involves me working for hours to create flowcharts in Google Docs using the drawing program. Yes, it works, but it's a very cumbersome way to create a flowchart. Thankfully, I recently discovered Lucidchart. more>>

The Readers' Choice issue is just around the corner, and we want to give everyone a chance to nominate their favorites before the vote. Have you stumbled across the most amazing game ever in 2014? Are you an Android developer that created the equivalent of digital sliced bread? Did you order a Linux-powered Borg implant on eBay, and think we all should be assimilated? more>>

Text expansion and hotkey automation are the sort of things you don't realize you need until you try them. Those of you who ever have played with system settings in order to change the function of a keystroke on you system understand the value of custom hotkeys. more>>

Sometimes a new piece of code turns out to be more useful than its author suspected. Alejandra Morales recently came out with the Cryogenic Project as part of his Master's thesis, supervised by Christian Grothoff. The idea was to reduce energy consumption by scheduling input/output operations in batches. more>>

If you're anything like me, your nightstand is full of electronic devices that need to be charged regularly. Every night I have:

• Nexus 7 tablet.

• Cell phone.

• Kindle Paperwhite.

• iPad Air.

• Fitbit. more>>

I use my phone more often to log in to on-line accounts than I use a computer. I can assure you it's not because typing passwords on a tiny keyboard is fun. For most of us, we just have instant access to our phones at any given time during the day. more>>

I'm writing this in a hotel room entered through two doors. The hall door is the normal kind: you stick a card in a slot, a light turns green, and the door unlocks. The inner one is three inches thick, has no lock and serves a single purpose: protection from an explosion. more>>

How'd You Do That?

Open-source advocates tend to make for rotten magicians. more>>

Gah, so frustrating! Ten years ago I wrote a rather popular book called Wicked Cool Shell Scripts, and I'm working on a new edition—a Tenth Anniversary release. There are lots of new scripts, entirely new chapters and updates to the older stuff. more>>

Vibrations and wave motions describe many different physical systems. In fact, most systems that dissipate energy do so through waves of one form or another. In this article, I take a look at gvb (Good ViBrations, http://www.pietrobattiston.it/gvb), a Linux application you can use to visualize and model wave motion and vibrations. more>>

I started writing for Linux Journal as a contributing editor in 1996 (here's one piece), and went full-time 1998, not long before I began co-writing The Cluetrain Manifesto with Chris Locke, David Weinberger and more>>
